Image display device
First Claim
1. An image display device, comprising:
- a first panel positioned to receive a first light beam and configured to modify the first light beam to emit a first modified light beam;
a first beamsplitter configured to reflect the first modified light beam;
a second panel positioned to receive a second light beam and configured to modify the second light beam to emit a second modified light beam;
a second beamsplitter configured to reflect the second modified light beam;
a third panel positioned to receive a third light beam and configured to modify the third light beam to emit a third modified light beam;
a third beamsplitter configured to reflect the third modified light beam;
a light combiner positioned to receive the first, second, and third modified light beams and configured to emit a combined light beam; and
a fourth panel positioned to receive the combined light beam and configured to emit a combined modified light beam.

Abstract
A color management system for use with projection displays includes, for example, two or more analyzers positioned to receive light beams as they are emitted from the panels of a color management system. The analyzers are positioned to receive the light beams directly from the image assimilators before the light has passed through another optical element such as a light combiner. The analyzers are configured for producing filtered light outputs with improved contrast relative to the incoming light beams. By positioning the analyzers to receive the light beams directly from the image assimilators, i.e., prior to passage through other optical elements, the analyzers are able to remove substantially all of the noise before it has become indistinguishable, on the basis of polarization, from the light that comprises the desirable image. Accordingly, this embodiment produces images having dramatically improved levels of contrast relative to prior art systems.
